Building an Arduino-based laser game, Part 3: Transmit, and that's a hit

Building an Arduino-based laser game, Part 3: Transmit, and that's a hit: "Arduino is an inexpensive, easy-to-use electronics platform. The entire platform, both the hardware and the software, is completely open source, and the language is loosely based on C/C++. Arduino was built for makers, tinkerers, and artists who want to take the plunge into creating interactive physical objects. This three-part series starts with basic Arduino hardware and uses it to create an interactive laser game called ''Duino tag,' where players can play tag using devices built nearly from scratch. In this final part of the 'Building an Arduino-based laser game' series, you'll build the transmitter and complete the 'Duino Tag gun."
